Key duplication system

A key-duplicating system comprises a network that includes a multiplicity of kiosks at a multiplicity of different locations, each of the kiosks having a customer interface and a processor coupled to the customer interface. A remote central server coupled to the kiosks is adapted to receive, from the kiosks, information identifying master keys to be duplicated. A key analysis module uses the information identifying master keys to be duplicated to derive information required to produce duplicates of the identified master keys, and a key duplicating module uses that information to produce duplicates of said identified master keys.
